CPU/GPU Benchmark
Benchmark your device's CPU and GPU performance right in your browser. Run JavaScript compute tests and WebGL rendering benchmarks to get a composite performance score — all locally, with no data sent to external servers.
Browser PrecisionMedium
CPU score from V8-optimized workloads (prime sieve, matrix multiply, string processing). GPU score from WebGL fragment-shader FPS. Results are relative to browser/JIT performance, not native benchmarks.
Frequently Asked Questions
How does the benchmark work?
The CPU test runs mathematical operations including prime number sieving, matrix multiplication, and string processing. The GPU test renders WebGL frames and measures FPS. A composite score combines both results with weighted factors.
Are browser benchmarks accurate?
Browser benchmarks provide a useful comparison between devices but are not as precise as native benchmarking tools. Results are affected by browser overhead, background processes, and thermal throttling.
Is the benchmark private?
Yes. All computations run locally in your browser. No performance data or device information is transmitted to any external server.
